    6969tachometer inputs to measure fan speed. Limit and status registers for all 
    7070measured values are included. The LM93 builds upon the functionality of 
    71 previous motherboard management ASICs and uses some of the LM85 s features 
     71previous motherboard management ASICs and uses some of the LM85's features 
    7272(i.e. smart tachometer mode). It also adds measurement and control support 
    7373for dynamic Vccp monitoring and PROCHOT. It is designed to monitor a dual 
    7474processor Xeon class motherboard with a minimum of external components.

    9993pectively.  Selecting a value not in this list will cause the driver to

    10195 
    10296#PROCHOT intervals: 0.73, 1.46, 2.9, 5.8, 11.7, 23.3, 46.6, 93.2, 186, 372

    109103The LM93 can also override the #PROCHOT pins by driving a PWM signal onto 
    110 one or both of them.  When overridden, the signal has a period of 3.56 mS, 
     104one or both of them.  When overridden, the signal has a period of 3.56 ms, 
    111105a minimum pulse width of 5 clocks (at 22.5kHz => 6.25% duty cycle), and 
    112106a maximum pulse width of 80 clocks (at 22.5kHz => 99.88% duty cycle).

    164158Automatic PWM: 
     
    172166#PROCHOT 1 & 2, and #VRDHOT 1 & 2.  The bindings are expressed as a bitmask 
    173167in the /proc files pwm<n>_auto_channels, where a "1" enables the binding, and 
    174  a "0" disables it. The h/w default is 0x0f (all temperatures bound).
